Abstract

An apparatus(1OO) and method for synthesizing nanostructures. In one embodiment, the apparatus includes a heating device(20) that defines a reaction zone inside bore(14) and a susceptor(30) made of a ferromagnetic material with a Curie temperature and placed in the reaction zone, where the Curie temperature substantially corresponds to a temperature at which the growth of desired nanostructures occurs and the heating device is capable of heating the susceptor substantially at the Curie temperature.
